Figure 5. (A) Schematic of the PSC architecture; (B) J-V characteristics of optimized PSCs with varying FTAC concentrations; (C) EQE responses and the associated integrated Jsc curves of different PSCs; (D) Continuous output performance of different PSCs; (E) Light-intensity-dependent open-circuit voltage of PSCs under 10-100 mW/cm2 of different PSCs; (F) Mott-Schottky plots (C-2-V) for various PSCs. FTAC: (Ferrocenylmethyl)trimethylammonium chloride; PCE: power conversion efficiency; PSCs: perovskite solar cells; J-V: current density-voltage; EQE: external quantum efficiency; ITO: indium tin oxide.
